Anyhow, the scenario that happened frequently on 10.3 for me without a panic was pulling the USB 3.0 ExpressCard together with an usb stick. That still leads to a panic on 11.0 + D8070: fault code = supervisor read data, page not present instruction pointer = 0x20:0xffffffff80ab48ca stack pointer = 0x28:0xfffffe022476ba20 frame pointer = 0x28:0xfffffe022476baa0 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 4 (doneq0) trap number = 12 panic: page fault cpuid = 1 KDB: stack backtrace: #0 0xffffffff80b24107 at kdb_backtrace+0x67 #1 0xffffffff80ad93e2 at vpanic+0x182 #2 0xffffffff80ad9253 at panic+0x43 #3 0xffffffff80fa0d31 at trap_fatal+0x351 #4 0xffffffff80fa0f23 at trap_pfault+0x1e3 #5 0xffffffff80fa04cc at trap+0x26c #6 0xffffffff80f841d1 at calltrap+0x8 #7 0xffffffff8030a879 at xpt_release_simq+0x79 #8 0xffffffff8030a649 at xpt_async_process+0x409 #9 0xffffffff8030b187 at xpt_done_process+0x807 #10 0xffffffff8030d916 at xpt_done_td+0x146 #11 0xffffffff80a90055 at fork_exit+0x85 #12 0xffffffff80f8467e at fork_trampoline+0xe Cheers, Jan Henrik
